By inserting an epitaxial in-plane buffer layer of Bi₅FeTi₃O₁₅, an artificial flux closure architecture enables ferroelectric polarization from a single unit cell of BaTiO₃ or BiFeO₃.

The discovery of passivating agents for perovskite photovoltaics can be an arduous and time-consuming process. Now, a machine-learning model is reported that accelerates the selection of bifunctional pseudo-halide passivators. The identified pseudo-halide passivators were experimentally shown to enhance the performance of perovskite solar cells.

Two-dimensional protein films, prepared via amyloid-like aggregation, can be made with nano- to meter-scale dimensions and features such as high interface adhesion, as well as tunable antibacterial, biomineralization and antifouling activity.

Conventional spectroscopic techniques are not sufficiently selective to follow the dynamics of trapped carriers in working perovskite solar cells. Here, authors use infrared optical activation spectroscopy to observe real time evolution of trapped carriers and compare the behaviour of trapped holes.

An article in Communications Engineering reports the development of menstrual pads made of a plant-based high-quality absorption material.

Carbon fibre blocks could make it easier to create uniform high temperature plasma for manufacturing and research.

Firms commercializing perovskite–silicon ‘tandem’ photovoltaics say that the panels will be more efficient and could lead to cheaper electricity.

Tool from Google DeepMind predicts nearly 400,000 stable substances, and an autonomous system learns to make them in the lab.
